The CAD model has been through many iterations, which worked on packaging, structural integrity, and ease-of-assembly. You can see the framing rails made of 1″ T-Slot extrusion, and the interior panels made of corrugated plastic board. It includes vacuum cups for increased stability. This model was taken to site visit #3, shown to the project partner, and approved. Since then, we have ordered materials and are preparing for fabrication!
